摘要:
Die Erfindung betrifft eine Scheibenbremse, insbesondere eine Reibungsbremse für Kraftfahrzeuge, mit einer Vorrichtung zur Bremsenkühlung. Zur Verhinderung einer unerwünschten Überhitzung bestimmter Komponenten umfasst eine derartige Scheibenbremse einen Bremssattel (1, 21, 41), der eine zugehörige Bremsscheibe sowie beiderseits der Bremsscheibe angeordnete Bremsbeläge übergreift und der zumindest eine Betätigungsvorrichtung (6) aufweist, sowie zumindest einen im Bremssattel (1, 21, 41) verlaufenden Kühlkanal (3, 23, 43) zur Durchströmung mit einem Kühlmedium, der eine Einlass-(4, 24, 44) und eine Auslassöffnung (5, 35, 45) aufweist. Eine Verstärkung des Kühleffekts wird dadurch erreicht, dass der Kühlkanal (3, 23, 43) im Innern des Bremssattels (1, 21, 41) unmittelbar entlang der Betätigungsvorrichtung (6) verläuft.
摘要:
The invention relates to an actuating unit for an electromechanically actuated disc brake for motor vehicles. Said actuating unit substantially comprises a drive unit (1) or an electromotor (10), an actuating element (7) which is used to engage one (4) of two friction linings (4, 5) which are displaceably mounted in a brake caliper, with a brake-disc (6) and a reduction gear (2). A freewheel mechanism (35) which co-operates with the electromotor (10) acts as a parking brake. In order to guarantee a high level of operational reliability for the parking brake and to make said parking brake resistant to external influences, in particular, oscillations or vibrations, the invention is characterised in that the freewheel mechanism (35) is configured in such a way, that its clamping action is produced by a positive-fit torque transfer and that, in its actuated state, it prevents a rotational movement of a bearing (24), in which the rotor (11) of the electromotor (10) is mounted.

The invention relates to an electromechanically operated disk brake for automobiles comprised of a floating brake caliper (1) and an actuating unit arranged on the brake caliper (1). The actuating unit (2) contains an electric motor (6) with a connected in series roller gear drive (7) which adjusts an actuating element (30) with a return path of the threaded rollers (12, 13, 14, 15). Said actuating element (30) brings one of the two displaceable friction linings (4, 5) which are arranged in the brake caliper (1) into contact with a disk brake (3). According to the invention, the spindle (16) of the roller gear drive (7) is operated by the electric motor (6) and the actuating element (30) is formed by the threaded nut (11) of said roller gear drive (7) in order to especially minimize the influence of disturbing force and movements.

The invention relates to an actuating unit for an electromechanically operable disc brake for motor vehicles. The actuating unit is comprised of a driving unit (1) or an electric motor (11), and an actuating element (15) by means of which one (4) of two friction linings (4, 5), said linings being arranged in a brake caliper such that they can be displaced, is brought into contact with a brake disc (6). The actuating unit additionally comprises a first and second reduction gears (2, 3). In order to decouple the second reduction gear (3) from the first reduction gear (2), the invention provides that the electric motor (11), the first reduction gear (2) and the second reduction gear (3) are designed as at least two components which can be handled separately.

摘要:
The invention concerns a motor vehicle disc brake which can be actuated electromechanically and comprises a floating calliper and an actuating unit disposed thereon. The actuating unit comprises an electric motor which, with the interposition of a reduction gear, adjusts an actuating element by means of which one of two friction linings displaceably disposed in the brake calliper are brought into engagement with a brake disc. According to the invention, in order to set the desired braking force individually, in particular when the disc brake is used on a motor vehicle, a force-measuring arrangement (23) is disposed in the power flow between the calliper (1) and the actuating unit (2). The output signals from the force-measuring arrangement (23) can be fed to a control circuit (26) which influences the voltage and/or the current fed to the electric motor (6).
摘要:
The inventive actuating unit for an electromechanical disc brake for a motor vehicle comprises a lever arrangement (3) placed between an actuating electric motor and a friction lining (4) of said disc brake. Said lever arrangement consists of a first lever (10) mounted at a level of a hinge point (A or 40) in a stationary manner with respect to a brake calliper (1), and a second lever (20) connected to an actuating element (7) by a driving force. Said actuating element is connected to the friction lining with the aid of an adjusting device (30) which is used for compensating the wear-out of the friction linings (4, 5). In order to reduce to a minimum the power demand of the electrical power drive system and the energy demand of the brake along the life service thereof, the adjusting device (30) is constructed in such a way that the efficient transmission range of the lever arrangement (10, 20) is carried into effect by modifying a deviation (A-C) between the hinge point (A or 40) and a force application point (C or 60) of the adjustment unit (30) to the actuating unit (7), the operating air gap between the friction lining (4, 5) and the brake pad (6) being maintained permanent.
摘要:
Disclosed is an actuating unit which can be used for an electromechanically actuatable disk brake for motor vehicles, essentially comprising a drive unit (1) or an electric motor (11), and an actuating element (7) which is used to cause two friction linings (4,5) which are displaceably arranged in a brake caliper to engage with a brake disc, in addition to a first and second reduction gear (2,3). Force is transmitted between the planetary cage (34) of the planetary gear (30-34) and the threaded spindle (17 or 22) of the ball screw (16-18) by means of a coupling shaft (40), whereby the ends thereof form universal joints (41,42) with the planetary cage (34 or 49) and the threaded spindle (22).
